Blower



T. C. RICHARDS, OF MILWAUKEE, lVISGONSIN.

BLOWER.

Specification of Letters Patent No. 26,863, dated January 17, 1860.

To all whom it may concern:

Be it known that I, T. C. RICHARDS, of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented a new and Improved Blower; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specication, in which-- Figure l is a central vertical sect-ion of a blower constructed according to my invention. Fig. 2 is a horizontal section of the same.

Similar letters of reterence indicate corresponding part's in both figures.

My improved blower consists of two 0r more chambers formed between an inner cylinder and an outer case by closing the space between them by means of flexible material so applied as to connect the ends of the cylinder` with the outer case and dividing said space lengthwise of the cylinder by partitions of flexible material, such chambers, formed between said partitions, being provided with suitable inlet valves, by which they receive air from the exterior of the outer case, and with outlet valves by which they communicate with a common discharge pipe. By giving the inner cylinder a movement of such character as to make it approach and recede from every part of the outer case in succession, the chambers are in turn expanded and contracted and so made to collect the air from without the outer case, compress it, and deliver it into the common discharge pipe from which it is discharged in a constant stream.

To enable others to make and use my invention I will proceed to describe its construction and operation.

A, is the outer case which is represented of upright cylindrical form, but which may be of other convenient form, made of wood or metal.

B, is the inner cylinder, which may be made of wood or metal either solid or hollow, but which in the example represented is made hollow to permit the use of the particular mode represented of obtaining its necessary movement. This cylinder has its sides parallel with the vertical sides of the case A.

C, C, are annular pieces of leather, or other Hexible material, impervious to air,

uniting the ends of the inner cylinder B, with the sides of the outer ease A, so as to make the space between them perfect-ly airtight, and made slack enough to permit the inner cylinder to move to and from all sides of the outer case.

D, D, are upright partitions made of leather, or other flexible impervious material dividing the space between the outer case and inner cylinder into several chambers E, E, said partitions being connected in such a manner as to form air-tight joints with the inner cylinder, the outer case and the flexible heads C, C, and being slack enough to admit of the before mentioned movement of the inner cylinder. The inner cylinder has casters or rollers f, f, attached to its bottom to support it upon the bottom ot` the casing A, and enable it to move freely.

a, a., are inlet openings, formed in the sides of thc outer casing A, for admitting air to the chambers E, E, each opening fitted with two valves Z), c, opening inward. The two valves may not in all cases be necessary, but one for each opening may be Suilicient.

(Z, eZ, are outlet openings., formed in the sides of the outer casing A, and each connected by one of a number of short pipes F, F, with a pipe G, which encircles the outer casing and from which branches 06f the discharge pipe or nozzle H. Each outlet openling is fitted with a valve e, Opening outwar I, is an upright shaft arranged in the center of the outer casing A, where it is fitted to suitable bearings in the top and bottom of said casing. To one side of this shaft there are attached rigidly within the cylinder B, two or more arms J, J, of equal length, each carrying a roller K, to press against the interior of the cylinder B. The arms J, J are of such length and the rollers K, K, of such diameter that the rollers bear upon one side of the cylinder while the shaft is very near the other side. The upper end of the shaft has attached to it a crank or other device by or through which to give it a rotary motion.

The rotary motion of the shaft I, and its arms causes the rollers K, K, to roll around the interior of the cylinder and by that means to give t-he cylinder a circular motion around the shaft I, without any rotary motion about its own axis, such circular motion being of such character that it (the cylinder 13,) approaches very near to and recedes pipeor nozzle H. As one or more chambers are always illing` and one or more always compressing and discharging the air, a steady blast from the pipe H,'is produced.

The blower instead of being arranged vertically, as shown, may be arranged hori- Zontally in which case each end of the cylinder B, may be furnished with rollers to roll against the heads -of the outer casing and thereby prevent any rubbing of the flexible heads C, C. Blowers constructed on this principle may be used for any of the ynumerous purposes forwhich other blowers or bellows are used, and will have the ad` Vantage over the ordinary fan blower of not requiring to be driven at so high a velocity.

What I claim as my invention, and desire to secure by Letters Patent, is

A blower composed of an inner cylinder and outer case connected by leather or other flexible substancev C, D, arranged substantially as /described to form two or more chambers between them, suchchambers being provided each with one' or more inlet valves to admit air from without, and with one or more outlet valves communicating with a common discharge pipe, and the inner cylinder having a circular motion within the outer case without rotating on its own axis, all substantially as herein set forth.
